     · Bond method The established technique for determining power requirements for ball mills is the Bond method (Bond 1961). This method also involves the application of some 'efficiency factors' as described by Rowland (1975). Bond's equation describes the specific power required to reduce a feed from a specified feed F80 to a product with a specified P80 4.

    Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding the ratio could vary between 1 1and 1.8 1.

    The critical requirement for the success of BCO is a good bond between a new and old concrete layers. If a good bond is provided the new slab consisting of old and new concrete layers will behave monolithically and increased slab thickness will reduce the wheel load stress at the bottom of the slab substantially thus prolonging the pavement life.
